Stainless steel composite fire-resistant steel bar and manufacturing method thereof
The invention discloses a stainless steel composite fire-resistant steel bar. The stainless steel composite fire-resistant steel bar comprises a stainless steel corrosion-resistant outer layer, a fire-resistant steel core and a metallurgical bonding transition layer, wherein the stainless steel corrosion-resistant outer layer is wrapped around the periphery of the fire-resistant steel core, after being assembled, the stainless steel corrosion-resistant outer layer and the fire-resistant steel core are subjected to hot rolling so that the stainless steel corrosion-resistant outer layer and the fire-resistant steel core can permeate mutually to form the metallurgical bonding transition layer, and the thickness ratio of the stainless steel corrosion-resistant outer layer to the fire-resistant steel core to the metallurgical bonding transition layer is 1: (10-200): (0.1-5).
本发明公开了一种不锈钢复合耐火钢筋，包括：不锈钢耐腐蚀外层、耐火钢钢芯和冶金结合过渡层，不锈钢耐腐蚀外层包覆在耐火钢钢芯外周，不锈钢耐腐蚀外层与耐火钢钢芯组坯后热轧使得两者相互渗透而形成冶金结合过渡层；不锈钢耐腐蚀外层、所述耐火钢钢芯与冶金结合过渡层的厚度之比为1：(10‑200)：(0.1‑5)。
